According to a survey, the probability that a family owns 2 cars if its annual income greater than $35000 is 0.75. Of the households surveyed 60 % had incomes over $ 35000 and 52 % had 2 cars? What is the probability that a family has 2 cars and an income over $35000 a year?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
